The first was disseminated by the Italian National Institute of Health (ISS) and the second, which is more usable due to the lower difficulty of calculation and the availability of data, was adopted by various regional and local institutions.The rationale for the Rt index refers to that for the R0 index, the basic reproduction number, which is used by infectivologists as a measure of contagiousness of a given infectious agent in a completely susceptible population. The RDt index, on the other hand, is borrowed from the techniques of time series analysis for the trend of an event measurement that develops as a function of time. The RDt index does not take into account the time of infection, but the date of the diagnosis of positivity and for this reason it is defined as diagnostic replication index, as it aims to describe the intensity of the development of frequency for cases recognizn, rather in the use of different information, i.e., the beginning of symptoms and the swabs outcome.Therefore, it is not appropriate to make a judgment of preference for one of the two indices, but only to invite people to understand their different potentials so that they can choose the one they consider the most appropriate for the purpose they want to use it for.the ability to implement effective preventive and control measures is rooted in public health surveillance to promptly identify and isolate contagious patients.
to describe some organizational aspects and resources involved in the control of COVID-19 pandemic.
observational cross sectional study.
a survey of methods and tools adopted by the competent service (Prevention department) in the Local public health units (LHU) of the regional Health services has been performed in May 2020. The survey collected data related to activities carried out during the month of April 2020 on the surveillance system for collection of suspected cases, their virological ascertainment, the isolation procedures and contact-tracing activities by means of an online questionnaire filled in by the public health structure of the regional health system. A convenience sample of Prevention departments was recruited.
in 44 Prevention departments of 14 Regions/Autonomous Provinces (caring for 40% of the population residing in Italcations and is a missed opportunity for the advancement of our knowledge on pandemic epidemiology analysis. In Italy, updating the pandemic response plans is the priority, at national, regional and local level, and the occasion to fill the gaps and to improve surveillance systems to the interruption of COVID-19 transmission.The fundamental moment of prosthetic rehabilitation is the "temporary". Although the meaning of the term diminishes its importance, the provisional has fundamental biological, aesthetic and functional functions. The oral cavity must maintain an adequate level of oral hygiene to carry out this delicate phase in the best possible way; a result achieved only with the collaboration of the prosthetic dentist with the hygienist and the patient, as if they were a biological system in motion. The different methods of hygiene are effective in maintaining a good level of oral health; but they could, if too aggressive, affect the prosthetic restoration. Our objective in vitro is to understand, after applying a known bacterial load, which hygiene method is the most effective in removing bacterial biofilm but at the same time is less aggressive towards resinous material.Cocaine is one of the most popular illicit drugs in Europe and cocaine-induced midline destructive lesions (CIMDL) represent a rare but destructive consequence of its intranasal use. The extent of lesions can vary remarkably and may include palate perforations with consequent oronasal reflux and hypernasal speech. The therapeutic options encompass surgery, with local and distant flaps, and prosthetic rehabilitation with palatal obturators. We retrospectively reviewed a case series of 6 patients affected by palatal perforation as part of CIMDL, who were treated with a dental or implant-retained palatal obturator at San Raffaele Dentistry Department between 2015 and 2020. In addition, we reviewed the available literature on CIMDL and the prosthetic rehabilitation of palatal perforations in this context. The most frequent symptoms reported were hypernasal speech, oro-nasal reflux, halitosis, and difficulty in interpersonal relationships. Palatal obturators were always successful in the relief of the majority of symptoms, but the duration of the benefit was strongly related to progression of the lesion, and in some cases a close follow-up and continuous modifications of the prosthesis were necessary. In conclusion prosthetic approach is a valid option for the symptomatic relief in CIMDL-related palate perforation. Nevertheless, the short-lasting efficacy for patients with active disease can be the reason for unsatisfactory results.The systematic analysis of parameters impacting implant primary stability is difficult to achieve with human cadavers or animal models, particularly for complex trans-sinus procedures to determine the effects of cortical layers and bone engagement on implant stability before and after a simulated load in vitro. Solid rigid polyurethane blocks, partially intersected by an 8-mm-thick space, were created to imitate tri-cortical situations, the presence of the sinus cavity, and the posterior maxilla with different degrees of bone atrophy. Implants were inserted through the cavity at an angle of 30˚ (scenarios 1 and 2) to imitate the clinical protocol. Controls simulating uni-cortical anchorage and no sinus cavity were also included (controls 1 and 2). Four parameters were measured peak insertion torque, insertion work, resistance to lateral bending loads and extraction torque. Scenarios 1 and 2 displayed similar peak insertion torque to control 2, where all three groups anchored equal amounts of bone surrogate. The distribution of surrogate bone in contact with trans-cavity implants influenced both extraction torque and the degree of lateral bending.
